JOSEPH E. BUEHLER, OF NET YORK, N. Y.

ROLLER WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 759,664, dated May 10, 1904.

Application filed April 25, 1903.

To all whom, it may cm1/cern.-

Be it known that I, Josera E. Buur-inne, a citizen of the UnitedStates, residing at New York, in the State of New York, have invented a new and Vuseful Roller Window-Screen, of which the following' is a specification.

This invention relates generally to windowscreens, and more particularly to a casing for containing a window-screen which is connected to the window-sash, so that when the sash 'is raised or lowered the screen will be withdrawn from its casing and iill the intervening spacebetween the sash and window-frame.

Various constructions of cases and means for connecting the screens to thc window frames and sashes have been devised; but these cases and means have not g'enerally been made adjustable to suit various widths of windows.

The object of my invention, therefore, is to provide a screen-casing which shall be adj ustable, whereby it can be fitted to any windowframe; and another object is to provide adjustable means both within the casing and upon the window-sash for the purpose vof securing the screen.

With these objects in view the invention consists inthe peculiar construction of the various parts and in their novel combination and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming part of this speci* ication, Figure 1 is a view showing' the practical application of my invention, the screens being applied to both the upper and lower ends of the window-frame. Fig'. 2 is a vertical sectional view illustrating the arrangement of the various parts. Fig. 3 is a horizontal sectional view of the casing and roller. Fig. 4 is a detail perspective View showing one of the journal-brackets for the screen-roller, the rod being detached from the socket-stud. Fig. 5 is a transverse sectional View taken through one of the upper roller-brackets, the position of the roller and screen being indicated in dotted lines. Fig. 6 is a detail perspective view of one of the adjustable clamping-strips employed to connect the end of the screen to the window-sash. Fig. 7 is a transverse sectional view of the said clamping-strip; and

Serial No. 154,331'. (No model.)

Fig. 8 is a detail sectional View illustrating the means of connecting the strip upon the screen.

Referring to the drawings, A indicates the window-frame, B the upper sash, and O the lower sash, all of which may be of the usual or any preferred construction. At the upper end of the window-frame and also at the lower end I arrange eases l), which are intended to contain the screens E when not in use, thc upper screen E being connected at its free end to the upper end of the lower sash, while the lower screen E is connected at its freev end to the lower end of the lower sash, as most clearly illustrated in Fig. 2. In making these connections Iemploy a special construction of screen and also special constructions of rollers and means for fastening the screens to the windowsashes. These features are the essential points of my invention, and in constructingthe said parts I employ box-like roller-brackets F, having ears or lugs F for attachment to the window-frame. Each roller-bracket is also provided with an inwardly-projecting stud F, one of said studs being threaded, as shown at F, to receive a rod (lr. The box-like brackets F are open at one side, as most clearly shown, the opposite side being formed with a guide F'L for the purpose of guiding the edge of the screen as it is rolled upon the roller. The box-like brackets F are secured at the Lipper and lower ends of the windo w-frame, at the sides thereof, and a metallic case H is litted between the said brackets, said case being preferably square in cross-section and of such size to snugly lit within the bracket F, said case having a slot H", which registers with the guide'Ft, so that the screen can pass freely in or out of the case, as desired. The case H is prefer: ably made in two or more sections telescop# ing into each other, as most clearly shown in Fig. 3, so that the said caselcan be made to lit any width of window-frame. is arranged within the case, said roller being preferably tubular in form and journaled upon the studsF, and this roller I is also made in sections which may bc connected by means of a supplemental roller I'. The rod G extends a considerable distance into one A roller I IOO A essai-y.

and secured to the window-sash and the end end of the roller I, and a coil-spring K is arranged within the tubular roller I and surrounds the said rod G, one end of said spring being secured to the inner end of the rod, while the other end of the spring' is secured to the roller, thereby producing a spring tension upon the roller for the purpose of keeping the screen sufciently tight at all times. The screen E is fastened at one end to roller I in any suitable manner. of the screen is preferably secured to a metallic strip L, which is secured within the clamp strip, fastened to the windowsash by means of the perforated ears or lugs L, said clamping-strip being essentially in the form of an inverted U with a compressed opening', so as to securely bind the end strip of the screen, and this clamp-strip L is also made in telescopic sections, so that it can be made to fit any width of window-sash. As

.before stated, the clamping-strip is fastened to the window-sash, the one connected to the lower screen being attached to the bottom rail of the lower sash, while the one connected to the upper screen is connected to the top rail of the upper sash.

While I have shown and described tw'o yscreens-namely, the upper and lower onescurely connecting the box-like brackets to the window-frame, no other connection being nec- The clamp-str1ps are then adjusted of the screen secured therein. rlhe device is then ready for operation, and it will be readily understood that as the sash is raised or lowered the screen will be rolled or unrolled from the case and will always screen the space intervening between the rail of the sash and the window-frame.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In adevice of the kind described, the combination with the adjustable case provided with The opposite end inwardly projecting studs, of a sectional spring-actuated roller mounted on said studs, said sections being connected by a supplemental roller, the adjustable sectional clampingstrip, the sections of which are approximately inverted-U-shaped, and the screen having one of its ends secured between the members of said clamping-strips and the other end connected to said roller, substantially as shown and described.

2. In a device of the kind described the combination with the box-shaped roller-bracket, provided with ears and with inwardly-projecting studs, one of said studs being threaded, a rod secured in said stud and having a coiled spring surrounding its projecting end, said spring having one of its ends secured to said rod and the other to the roller, a sectional roller journaled on said studs, said roller carrying a screen, the free end of which is secured in the sectional clamping-strip, said strip being provided with ears, substantially as described. l

3. In adevice of the kind described, the com bination with the boX-like brackets having guides and also provided with inwardly-projecting studs, the sectional telescopic case arranged between the boX-like brackets, theltubular adjustable roller journaled upon the studs, the coil-spring arranged within the roller and adapted to exert a torsional strain thereon, and the adjustable clamping-strip provided with perforated ears or lugs, and the screen arranged between the said strip and the spring-actuated roller, substantially as described.

4. The combination with the box-like brackets having guides and studs, of the sectional telescopic case arranged between the brackets, the sectional tubular roller journaled` upon the studs and the brackets and rod secured to one of the studs and projecting into the roller, a coil-spring surrounding the rod and attached thereto at one end, the opposite end of said spring' being connected to the roller all arranged and adapted to operate substantially as described.
